codes.
Safety recommendations
To avoid any equipment damage or bodily injury, read the following safety recommendations before
installation. The recommendations do not cover every possible hazardous condition.
•To avoid damage to the electrolytic capacitor in the switch, do not store the switch without
power for more than one year.
•Before cleaning the switch, remove all power cords from the switch. Do not clean the switch
with a wet cloth or liquid.
•Do not place the switch near water or in a damp environment. Prevent water or moisture from
entering the switch chassis.
•Do not place the switch on an unstable case or desk. The switch might be severely damaged in
case of a fall.
•Ensure good ventilation of the equipment room and keep the air inlet and outlet vents of the
switch free of obstruction.
•Make sure the operating voltage is in the required range.
•To avoid electrical shocks, do not open the chassis while the switch is operating or when the
switch is just powered off.
•The accessories shipped with the switch, including but not limited to power cables, are intended
only for the switch. Please do not use them for other products.
Examining the installation site
The switches must be used indoors. You can mount your switch in a rack or on a workbench, but
make sure:
•A minimum clearance of 5 cm (1.97 in) is reserved at the air inlet and exhaust vents for
ventilation.

2
•The rack or workbench has a good ventilation system.
•The rack or workbench is sturdy enough to support the switch and its accessories.
•The rack or workbench is reliably grounded.
To ensure correct operation and long service life of your switch, install it in an environment that meets
the requirements described in the following subsections.
Temperature/humidity
Maintain temperature and humidity in the equipment room as described in "Technical specifications."
•Lasting high relative humidity can cause poor insulation, electricity creepage, mechanical
property change of materials, and metal corrosion.
•Lasting low relative humidity can cause washer contraction and ESD and bring problems
including loose captive screws and circuit failure.
•High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the switch.
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points, especially when indoor relative humidity is low. In the worst
case, electrostatic adsorption can cause communication failure.
Table 2 Dust concentration limit in the equipment room
Substance Concentration limit (particles/m³)
Dust ≤3 x 104 (no visible dust on the tabletop over three days)
NOTE:
Dust diameter ≥5 μm
The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion
and premature aging of components, as shown in Tabl e 3.
Table 3 Harmful gas limits in the equipment room
Gas Maximum concentration (mg/m3)
SO20.2
H2S 0.006
NH30.05
Cl20.01
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in the following ways:
•A conduction pattern of capacitance coupling.
•Inductance coupling.
•Electromagnetic wave radiation.
•Common impedance (including the grounding system) coupling.

3
To prevent EMI, perform the following tasks:
•If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE)
to filter interference from the power grid.
•Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
•Use electromagnetic shielding, for example, shielded interface cables, when necessary.

4
Installing the switch
WARNING!
Before installing or moving the switch, remove the power cord.
You can install an HPE 1910 switch in a 19-inch rack, on a workbench, or on a wall.
Mounting the switch in a 19-inch rack by using
mounting brackets
1. Wear an ESD wrist strap and make sure it makes good skin contact and is reliably grounded.
2. Verify that the rack is securely grounded and is stable.
3. Select mounting brackets for the switch.
{The HPE 1910 8 switch uses Type-A mounting brackets, as shown in Figure 1.
{The HPE 1910 8 PoE+ switch uses Type-B mounting brackets, as shown in Figure 2.
{The HPE 1910 24 PoE+, 1910 24, and 1910 48 switches use Type-C mounting brackets, as
shown in Figure 3.
4. Attach the mounting brackets to both sides of the chassis with screws.
NOTE:
Mounting brackets are used only for securing the switch to the rack. A rack shelf on the rack is
used to bear the switch weight.

Mounting the switch on a workbench
IMPORTANT:
•Reserve a clearance of 10 cm (3.9 in) around the chassis for heat dissipation.
•Do not place heavy objects on the switch.
To mount the switch on a workbench:
1. Verify that the workbench is sturdy and reliably grounded.
2. Place the switch bottom up, and clean the round holes in the chassis bottom with a dry cloth.
3. Attach the rubber feet to the four round holes in the chassis bottom.
4. Place the switch upside up on the workbench.
Figure 7 Attaching rubber feet (HPE 1910 24 PoE+ Switch)
Mounting the switch on a wall
Only the HPE 1910 8 switch can be installed on a wall. The type of screws used to mount the switch
on the wall depends on the wall type. This section uses a concrete wall as an example.
Wall-mounting anchor kits are user supplied. The screws must be a minimum of 3 mm (0.12 in) in
diameter, and the screw head must be a minimum of 6 mm (0.24 in) in diameter.
Figure 8 Wall-mounting anchor kit
To install the switch on a concrete wall:
1. Drill two holes at the same height. Make sure the spacing in between is 160 mm (6.30 in), as
shown in Figure 9.
The hole depth and diameter depend on the wall anchors and screws you use. Make sure you
can push the anchors to their full depth in the holes.

8
Figure 9 Hole spacing
2. Insert one wall anchor into each hole until the anchors are flush with the wall surface.
3. Drive one screw into each wall anchor, and tighten the screws just enough to keep it secure in
the wall anchor.
Leave a minimum clearance of 1.5 mm (0.06 in) between the base of the screw head and the
wall anchor so the switch can hang on the screws securely.
Figure 10 Driving a screw into a wall anchor
4. Align the two mounting holes in the switch chassis bottom with the two screws on the wall and
hang the switch.
Make sure the Ethernet ports are facing downwards and the chassis side panels are
perpendicular to the ground.
